Is mcSound the instance name of a valid movie clip? What happens if you use the trace() function to trace the value of h (your Sound instance) in the stopVideo() function?

e.g.

function stopVideo():Void {
  media.stop();
  trace(h);
  h.start();
}

My purpose to stop start background music is when I load the flv file I want the backgraound music to stop.After I stop the flv movie then I want to start the background again.

I had put your sample code with the stop start flv action script.
The problem is when the flv movie start the script stop the back ground music.

But When I stop the flv movie .The Background music is not start.
Please advice me

Here is my sample code.

var h:Sound = new Sound(mcSound);
h.attachSound(”bg1″);

function onInit(){
if( visible )
playVideo();
}

function onOpen(){
playVideo();
}

function onClose(){
stopVideo();
}

function playVideo(){
media.play();
h.stop();

}

function stopVideo(){
media.stop();
h.start();
}
